Housings for electrical installation equipment

The invention relates to a housing for electrical installation devices Consists of a can and a lid made of elastic material, which is placed on the upper edge of the can rests sealingly and embraces this with a collar-like extension, the cover with on opposite sides Locking lugs formed on the inside of the extension on corresponding locking lugs on the outside of the upper edge of the can is held and with engagement points provided in the area of the locking lugs for introducing a locking mechanism loosening tool.

In a known housing of the type described (DE-GM 67 51 595) are the latches formed on the lid and the can noses formed by means of a relatively complex tool since they are expensive and prone to repair for their molding Sideshifter needed to be grounded. A loosening of the lid from the can by means of a tool is possible in this known housing only possible from the side of the housing wall. However, side access is possible depending on the installation location of the housing not given to the housing, so that the use of this housing is limited only to those cases where the side wall the housing remains freely accessible.

The invention has therefore set itself the task of creating a housing in which the lid on the can also is held by a latching connection which can only be released by a tool, but with a release of the cover from the Front side of the housing is made possible. This means that the housing can also be installed in places where subsequent access from the side is not possible

is, ζ. B. in niches or similar places. In addition, cans and lids should be made in simple molds be able to be created without the need for special shaping means such as Sideshifts or the like are required.

According to the invention this is achieved in that the locking lugs on the upper edge of the can over the outer wall of the can protrude completely and this can wall is tapered towards the bottom of the can and that the locking lugs on the lid are formed by a recess penetrating the surface of the lid and this recess engages rush for the tool forms.

According to a further embodiment, the recesses are located within an outer frame of the cover and from an actuating element, viewing element or hinged cover located within the frame, one arranged in the housing Installation device, such as switch, socket or the like. covered.

According to another embodiment, the recesses are the surface of the cover wholly or partially overlapping actuating, viewing element or hinged cover eini Installation devices arranged in the housing, such as switches, sockets or the like. Covered.

The invention is illustrated in the drawing using exemplary embodiments. It shows:

Fig. 4 shows a further cross section of the housing with a further Ausgestal processing shape,

5 shows a top view of the cover according to FIGS. 4 and 5

FIG. 6 shows a longitudinal section through the cover according to FIG. 4.

The can 1, which consists of a thermosetting insulating material ", but can optionally also be made of a thermoplastic insulating material, has latching lugs 5 on opposite sides of its upper edge 3 of the can. These protrude completely beyond the outer wall 6 of the can 1, so that they can be produced in a compression or injection molding tool using the normal counter-compression process. For better shaping, the outer wall 6 of the can 1 is tapered in the direction of the can bottom comprehensive crag-like extension 4. Latching lugs 7 are formed on opposite inner sides of this extension 4, which engage behind the latching lugs 5 when the lid 2 is pressed onto the box 1. With normal installation devices, only two latching lugs are required for reliable attachment of the lid 2 to the box 1 5 or 7 required Above the locking lugs 7 of the lid 2 recesses E are provided which are open to the surface of the cover 2. As a result, the locking lugs 7 of the lid can also be formed in the normal counterpressing process in a pressing or injection molding tool. Through the recesses 8, engagement points 9 are formed for the attack of the tool 10 in order to be able to release the latching by means of this tool.

The recesses 8, which are thus accessible from the surface of the cover 2, can be used in the formation of the housing -6-

for a switch, a lamp, a socket or a similar installation device according to FIG corresponding installation device associated actuating visual element or hinged cover 11 are covered. This actuating element, viewing element or hinged cover 11 overlap the surface of the cover 2 in whole or in part.

4 to 6 show a further embodiment which represents a housing for a switch.

The cover 2 has an outer frame 12 within which, in the example, the actuating rocker 11 is one Switch rests, which can engage with its side walls 13 directly on the inside of the frame. the Actuating rocker 11 can be mounted pivotably with molded bearing webs 14 on pins 15 of cover 2. Through this training, the recesses 8 of the cover 2 are also deprived of a direct view and for an actuation for releasing the lid 2 from the can 1 is immediately accessible after removing the rocker switch 11

For a seal between can 1 and lid 2, Qe If necessary, a sealing ring 16 or the like. Provided will.
